The market offers battery swapping equipment that directly swaps batteries for electric devices. This equipment consists of a battery swapping robot and a charging compartment. The charging compartment contains battery holders that hold and charge the battery boxes. However, not all of these holders can be used to store the battery boxes; space needs to be reserved for temporarily storing depleted battery boxes removed from the battery swapping vehicle.

[0073] Example 1

[0074] See Figures 1 to 24 As shown in the illustration, this application provides a battery swapping device, including a battery swapping robot 9 and a battery box storage seat 7. The battery swapping robot 9 can reciprocate along a set trajectory, and the battery swapping robot 9 has a gripping mechanism for gripping battery boxes. The battery box storage seat 7 is located on the set trajectory, and the battery box storage seat 7 is used to temporarily store the battery boxes gripped by the battery swapping robot 9. By setting the battery box storage seat 7 on the set trajectory, this application can temporarily store battery boxes removed from vehicles to be swapped, eliminating the need to reserve empty space in the charging compartment 200 of the battery swapping device, allowing the charging compartment 200 to remain fully loaded with battery boxes, thereby increasing the battery box loading capacity of the charging compartment.

[0075] In one possible implementation, see Figures 1 to 3 As shown, the battery swapping equipment includes at least two battery storage seats 7, each of which is arranged sequentially along the set trajectory, and there is a battery swapping station between the at least two battery storage seats for the battery swapping robot 9 to perform battery swapping actions.

[0076] By setting up battery storage seats 7 on both sides of the battery swapping station, the battery swapping robot 9 can place the depleted battery box from the vehicle to be swapped onto the corresponding battery storage seat 7 according to the location of the target fully charged battery box. For example, when the battery swapping robot 9 needs to grab a fully charged battery box located on the left side of the battery swapping station, it can first grab the depleted battery box from the vehicle to be swapped and place it on the battery storage seat 7 on the right side of the battery swapping station, without obstructing the subsequent movement of the battery swapping robot 9 to the left. This facilitates the smooth completion of the battery swapping task by the battery swapping robot 9.

[0077] In one possible implementation, the extension length of the battery swapping station along the predetermined trajectory is not less than the extension length of the battery storage base 7 or the battery box itself. Thus, during the process of the battery swapping robot 9 picking up a fully charged battery box, moving it to the battery swapping station, and translating the battery box along the predetermined trajectory, the fully charged battery box will not interfere with the depleted battery box on the battery storage base 7, ensuring safety during the battery swapping process. The predetermined trajectory can be along the length of the battery swapping compartment of the battery swapping equipment.

[0078] In one possible implementation, the battery swapping robot 9 has a walking mechanism that drives the robot 9 to move towards another battery storage seat 7 to grab a target fully charged battery box when the robot 9 transfers a depleted battery box from the vehicle to be swapped to one of the battery box storage seats 7. The walking mechanism can be wheels installed at the bottom of the battery swapping robot.

[0079] In this implementation plan, during the battery swapping process, the battery swapping robot 9 places the battery box in the opposite position to the battery box storage seat 7 where the depleted battery box is placed, and the target fully charged battery box that the battery swapping robot 9 is grabbing. This ensures that the depleted battery box does not block the battery swapping robot 9 from grabbing the fully charged battery box, and ensures that the battery swapping task is completed smoothly.

[0080] See Figure 1 As shown, the battery swapping equipment also has multiple battery box mounting bases 2120, each of which is located on one side of the set trajectory, and the battery box mounting bases 2120 are arranged sequentially along the set trajectory. Each battery box mounting base 2120 can be installed inside the charging compartment 200.

[0081] In one possible implementation, see Figure 3 As shown, the gripping mechanism includes a multi-stage telescopic boom 91 and a gripper 92, with the gripper 92 connected to the end of the multi-stage telescopic boom 91. The multi-stage telescopic boom 91 can extend and retract bidirectionally along a direction perpendicular to a set track to transfer a depleted battery box on one side of the set track to the battery box storage seat 7, transfer a fully charged battery box on the battery box fixing seat 2120 on the other side of the set track to the battery box waiting vehicle, and transfer a depleted battery box on the battery box storage seat 7 to the battery box fixing seat 2120.

[0082] The battery swapping robot 9 has two side movable frames 93, which are arranged alternately along a direction perpendicular to a predetermined trajectory. The gripping mechanism is connected to the two side movable frames 93. The distance between the two side movable frames 93 along the direction perpendicular to the predetermined trajectory is greater than the length of the battery storage base 7. The battery swapping robot 9 can move along the predetermined trajectory past the battery storage base 7 without interfering with it.

[0083] Each of the side-mounted movable frames 93 includes two uprights 931, which are arranged sequentially along the length of the predetermined trajectory, with a clearance space between them to avoid the battery box. During the retraction and extension of the multi-stage telescopic boom 91 along a direction perpendicular to the predetermined trajectory, the grabbed battery box can pass smoothly between the two uprights 931 without interfering with them.

[0084] In one possible implementation, the battery swapping device includes two guide rails 16 extending along the predetermined trajectory, with the two guide rails spaced apart. A battery storage seat 7 is disposed between the two guide rails 16. The battery swapping robot 9 is movably connected to the two guide rails. Two side movable frames 93 of the battery swapping robot 9 are slidably connected to the two guide rails respectively, and two uprights 931 of the side movable frames 93 are sequentially arranged along the length of the guide rails. The battery storage seat 7, disposed between the two guide rails, does not obstruct the movement of the battery swapping robot 9 along the guide rails.

[0085] In one possible implementation, see Figure 4 and Figure 5 The battery box temporary storage seat 7 extends in a direction perpendicular to the guide rail. The battery box temporary storage seat 7 and the battery box fixing seat 2120 in the charging compartment are arranged in the same orientation, which makes it convenient for the battery swapping robot 9 to perform unified actions to pick up and put down the battery box on the battery box fixing seat 2120 and the battery box temporary storage seat 7.

[0086] In one possible implementation, the battery storage holder 7 has a horizontal frame 71 and a guide assembly protruding from the horizontal frame 71. The battery box can slide along the guide assembly onto the horizontal frame 71.

[0087] The battery swapping robot 9 is also equipped with a lifting mechanism, and the gripper 92 is connected to the lifting mechanism. The lifting mechanism can drive the gripper 92 to move up and down. When it is necessary to put the battery box into the battery box temporary storage seat 7, the multi-stage telescopic boom 91 is first in the retracted state. The lifting mechanism gradually lowers the gripper 92 so that the battery box contacts the guide component and gradually falls along the guide component until it is stably supported on the battery box temporary storage seat 7.

[0088] In one possible implementation, the guiding assembly includes a plurality of guide bodies 72, each guide body 72 being distributed at different positions on the frame body, and each guide body 72 having an inclined guiding surface. The battery box can slide down the bottom periphery along the guiding surface until it is stably supported by the horizontal frame 71 of the battery box temporary storage seat 7. In addition to its guiding function, the guide body 72 also serves a limiting function, preventing the battery box from shifting or tilting.

[0089] Example 2

[0090] See Figures 2 to 6As shown in Embodiment 2 of this application, the battery swapping equipment is further described. The battery swapping equipment includes a battery swapping compartment 100 and a charging compartment. The battery swapping compartment 100 includes: a base frame 8, a compartment shell 1, a battery box storage seat 7, and a battery swapping robot 9. The compartment shell 1 is detachably connected to the base frame 8, and the compartment shell 1 has a cavity. The battery box storage seat 7 is disposed within the cavity. The battery swapping robot 9 is movably disposed within the compartment shell 1, and the battery swapping robot 9 can grasp the battery box and temporarily store it in the battery box storage seat 7.

[0091] The battery swapping equipment includes a battery swapping compartment 100 and a charging compartment. The charging compartment contains multiple battery box mounting brackets for securing the battery boxes and charging them. In this embodiment, by providing a battery box storage seat 7 within the casing 1 of the battery swapping compartment 100, depleted battery boxes removed from the vehicle to be swapped can be temporarily stored. This eliminates the need to reserve empty space within the charging compartment, allowing it to remain fully loaded with battery boxes, thus maximizing the space of the battery swapping compartment 100 and increasing its battery box loading capacity.

[0092] In one possible implementation, see Figure 2 and Figure 6 As shown, the battery swapping compartment 100 includes two battery storage seats 7. The compartment shell 1 has a side wall 11 and a top wall 13. The side wall 11 extends along the edge of the bottom frame 8. The top wall 13 is connected to the side wall 11. A doorway 12 is provided on the side wall 11. The two battery storage seats 7 are located in the cavity and are respectively located on both sides of the doorway 12.

[0093] The battery swapping compartment 100 and the charging compartment 200 are arranged parallel to each other. A doorway 12 is provided on the side of the battery swapping compartment 100 facing away from the charging compartment, and the side of the battery swapping compartment 100 facing the charging compartment is an open side, which is connected to the charging compartment. The battery swapping robot 9 has a gripping mechanism for grasping battery boxes. The gripping mechanism includes a multi-stage telescopic arm 91 and a gripper 92. The gripper 92 is connected to the end of the multi-stage telescopic arm 91, which can extend and retract along the width of the battery swapping compartment 100. During the battery swapping process, the multi-stage telescopic arm 91 of the battery swapping robot 9 extends out of the doorway 12, allowing the gripper 92 to contact and grasp the depleted battery box on the vehicle to be swapped. Then, the battery swapping robot 9 controls the multi-stage telescopic arm 91 to retract the battery box from the doorway 12 into the cavity for storage in the battery box temporary storage seat 7. Subsequently, the battery swapping robot 9 moves horizontally along the length of the battery swapping compartment to the target position and controls the multi-stage telescopic boom 91 to extend to one side of the charging compartment to grab the target battery box inside the charging compartment using a gripper. Then, the multi-stage telescopic boom 91 drives the fully charged battery box to retract into the cavity. The battery swapping robot moves to the position between the two battery box temporary storage seats 7, that is, the position directly opposite the doorway 12, which can also be called the power supply station. At this position, the battery swapping robot controls the multi-stage telescopic boom 91 to extend the fully charged battery box out of the doorway to load the battery box onto the battery swapping vehicle. Finally, the battery swapping robot grabs the depleted battery box stored on the battery box temporary storage seat and loads it into the battery box fixing seat in the charging compartment to charge the battery box.

[0094] By setting up temporary battery storage seats on both sides of the battery swapping station, the battery swapping robot can place the battery box it grabs from the vehicle to be swapped onto the corresponding temporary storage seat, based on the location of the target fully charged battery box. For example, when the battery swapping robot needs to grab a fully charged battery box located on the left side of the battery swapping station, it can first grab a depleted battery box from the vehicle to be swapped and place it on the temporary storage seat on the right side of the battery swapping station, without obstructing the robot's subsequent movement path. This facilitates the smooth completion of the battery swapping task by the battery swapping robot.

[0095] In one possible implementation, the housing 1 has a bottom wall 15, the side wall 11 is connected to the bottom wall 15, and the battery storage seat 7 is fixed to the bottom wall 15.

[0096] A door 2 is provided on the side wall 11, and the door 2 is slidably connected to the side wall 11 to open or close the door opening 12.

[0097] The bottom wall 15 has multiple first-direction bottom beams, which can extend along the length of the battery swapping compartment. Adjacent first-direction beams are connected by second-direction beams, which are perpendicular to the first-direction beams. The battery storage seat 7 is positioned perpendicular to the first-direction beams, supported on the first-direction beams, and fixed to the second-direction beams by fasteners. A panel layer covers the bottom wall 15 on the first and second-direction beams, and fasteners pass through the panel layer and are connected to the second-direction beams.

[0098] See Figure 3 As shown, the battery swapping compartment 100 also includes two guide rails 16, which are spaced apart on the bottom wall 15. The battery storage seat 7 is located between the two guide rails 16, and the battery swapping robot 9 is slidably connected to the two guide rails 16. The battery storage seat 7 does not interfere with the operation of the battery swapping robot.

[0099] Optionally, the sidewall 11 includes a first sidewall and two second sidewalls, located at both ends of the battery swapping compartment along its length. The first sidewall connects to the two second sidewalls, and the top wall 13 connects to both the first sidewall and the two second sidewalls. The side of the compartment shell 1 opposite to the first sidewall is an open side. The battery swapping robot 9 has a gripping mechanism that can extend and retract bidirectionally along a direction perpendicular to the first sidewall to extend or retract the open side / doorway 12.

[0100] The battery swapping compartment 100 also includes a cover 14, and a hoisting clearance hole 132 is provided on the top wall 13. The cover 14 is detachably connected to the top wall 13 to close or open the hoisting clearance hole 132.

[0101] The battery swapping compartment 100 of this application has a lifting clearance hole 132 on its top wall 13, which facilitates the assembly of the battery swapping robot 9. A lifting rope is connected to the battery swapping robot, passing through the lifting clearance hole 132 and connecting to a lifting device. The operator uses a translation mechanism to first insert one long side of the battery swapping robot 9 into the cavity, positioning it below the lifting clearance hole 132. The lifting device then lifts the battery swapping robot 9, rotates it 90 degrees to make it upright (when the battery swapping robot 9 is in the upright position, its long side is perpendicular to the length direction of the battery swapping compartment 100). The lifting device then lowers the battery swapping robot 9 to complete its assembly. The cover 14 can close the lifting clearance hole 132 after the battery swapping robot 9 is assembled to prevent rainwater from seeping into the battery swapping compartment 100.

[0102] In one possible implementation, a light-transmitting groove is formed in the middle of the cover 14, and a light-transmitting plate is connected to the cover 14, covering the light-transmitting groove. Through the design of the light-transmitting plate, sunlight can pass through it and illuminate the battery swapping compartment 100, resulting in better lighting inside the compartment.

[0103] Optionally, the base frame 8 is provided with a guide component (not shown). During the process of the compartment shell 1 being installed into the base frame 8, the compartment shell 1 can slide along the guide component until it is supported by the base frame 8. Optionally, the guide component has an upwardly convex arc-shaped guide surface, and the bottom of the compartment shell 1 is provided with a guide mating hole (not shown). During the process of the compartment shell 1 being installed into the base frame 8, the guide component can be inserted into the guide mating hole.

[0104] In this implementation scheme, guide components are provided to facilitate accurate assembly of the silo shell 1. Lifting rings can be installed on the silo shell 1 for lifting and lowering using lifting equipment.

[0105] The battery swapping robot 9's gripping mechanism also includes a lifting mechanism, which is located at the end of the multi-stage telescopic boom 91. The gripper 92 is connected to the lifting mechanism, which drives the gripper 92 to move up and down, allowing it to grip or release the battery box. When gripping a battery box, the multi-stage telescopic boom 91 extends and retracts, positioning the gripper 92 directly above the battery box. Then, the lifting mechanism lowers the gripper 92 to contact and grip the battery box. Subsequently, the lifting mechanism raises the gripper 92 to lift the battery box. When transferring the battery box to the battery box mounting base or battery box temporary storage base 7, the multi-stage telescopic boom 91 first retracts the battery box. Then, the entire battery swapping robot 9 moves along the guide rail to the target position. The multi-stage telescopic boom 91 extends again, positioning the gripper 92 directly above the corresponding battery box temporary storage base 7 or battery box mounting base. Then, the lifting mechanism lowers the gripper 92 to load the battery box into the battery box temporary storage base 7 or battery box mounting base, and the gripper 92 releases the battery box.

[0106] It should be noted that the battery swapping robot has been patented and published, and its specific structure will not be described in detail here. Furthermore, various forms of battery swapping robots are applicable to this application, and this application does not limit the specific structure of the battery swapping robot.

[0107] In one possible implementation, see Figure 4 As shown, the battery storage holder 7 has a horizontal frame 71 and a guide assembly protruding from the horizontal frame 71. The battery box can slide along the guide assembly onto the horizontal frame 71.

[0108] The battery swapping robot 9 is also equipped with a lifting mechanism, and the gripper 92 is connected to the lifting mechanism. The lifting mechanism can drive the gripper 92 to move up and down. When it is necessary to put the battery box into the battery box temporary storage seat 7, the multi-stage telescopic boom 91 is first in the retracted state. The lifting mechanism (which may include a lifting rope) gradually lowers the gripper 92 to contact the battery box with the guide assembly and gradually falls along the guide body 72 until it is stably supported on the battery box temporary storage seat 7.

[0109] In one possible implementation, the guiding assembly includes a plurality of guide bodies 72, each guide body 72 being distributed at different positions on the frame body, and each guide body 72 having an inclined guiding surface. The battery box can slide down the bottom periphery along the guiding surface until it is stably supported by the horizontal frame 71 of the battery box temporary storage seat 7. In addition to its guiding function, the guide body 72 also serves a limiting function, preventing the battery box from shifting or tilting.

[0110] Example 3

[0111] See Figures 7 to 11 As shown in the illustration, this application embodiment continues to describe the structure of the battery swapping compartment 100 in detail. The battery swapping compartment 100 includes: a side wall, a top wall 13, and a cover 14. The top wall 13 is connected to the side wall, and the top wall 13 and the side wall enclose a cavity. The top wall 13 is provided with a lifting clearance hole 132 communicating with the cavity. The cover 14 is detachably connected to the top wall 13 to close or open the lifting clearance hole 132.

[0112] The battery swapping compartment 100 of this application has a lifting clearance hole 132 on its top wall 13, which facilitates the assembly of the battery swapping robot. A lifting rope is connected to the battery swapping robot, passing through the lifting clearance hole 132 and connecting to a lifting device. The operator uses a translation mechanism to first insert one long side of the battery swapping robot into the cavity below the lifting clearance hole. The lifting device then lifts the battery swapping robot, rotates it 90 degrees to make it upright (when the battery swapping robot is upright, its long side is perpendicular to the length direction of the battery swapping compartment 100). The lifting device then lowers the battery swapping robot to complete the assembly. The cover 14 can close the lifting clearance hole 132 after the battery swapping robot is assembled to prevent rainwater from seeping into the battery swapping compartment 100.

[0113] In one possible implementation, the top wall 13 has a top frame and a cover plate assembly, the cover plate assembly covering the top frame, and the lifting clearance hole 132 is formed between the cover plate assemblies.

[0114] The cover plate assembly may have a central opening to form the lifting clearance hole 132. Alternatively, the cover plate assembly includes a first side cover plate 133 and a second side cover plate 134. Both the first side cover plate 133 and the second side cover plate 134 cover the top frame. The lifting clearance hole 132 is formed between the first side cover plate 133 and the second side cover plate 134. The first side cover plate 133 and the second side cover plate 134 may both be integral plates. Alternatively, the first side cover plate 133 and the second side cover plate 134 may both be formed by splicing multiple plates.

[0115] In one possible implementation, see Figure 8 , Figure 10 and Figure 11 As shown, the top wall 13 has a cover fitting frame 135, which is arranged along the edge of the hoisting clearance hole 132. The cover 14 is detachably connected to the cover fitting frame 135. The design of the cover fitting frame 135 facilitates the assembly and disassembly of the cover 14.

[0116] In one possible implementation, see Figure 9 and Figure 11 As shown, the top wall 13 has a top frame, which includes two main beams 131a spaced apart. The cover fitting frame 135 has two first fitting beams 1351 and two second fitting beams 1352. The two first fitting beams 1351 are vertically connected to the two main beams 131a, and the two second fitting beams 1352 are respectively disposed on the two main beams 131a, with their ends connected to the two first fitting beams 1351. The cover 14 is supported on the first fitting beams 1351 and the second fitting beams 1352. In this embodiment, the two first fitting beams 1351 and the two second fitting beams 1352 of the cover fitting frame enclose a U-shaped opening. The fitting beams in both directions provide a stable supporting position for the cover.

[0117] In one possible implementation, the top frame includes a plurality of crossbeams 131b, each of which is connected to two of the main beams 131a. The first mating beam 1351 and one of the crossbeams 131b are fitted together.

[0118] In this embodiment, the first mating beam 1351 can be directly connected and fixed to the crossbeam 131b, which improves the structural strength of the first mating beam 1351. The first mating beam 1351 can be fixed to the crossbeam 131b by welding. Alternatively, the first mating beam 1351 can be fixed to the crossbeam 131b by fasteners.

[0119] In one possible implementation, the cover fitting frame 135 has an upper extension plate 135a. For example, upper extension plates 135a are provided on both the first fitting beam 1351 and the second fitting beam 1352. A lower extension plate (not shown) is provided along one periphery of the cover 14. When the cover 14 is installed on the cover fitting frame 135, the lower extension plate and the upper extension plate 135a are in contact.

[0120] In this embodiment, with the cover 14 installed on the cover fitting frame 135, the lower extension plate can be sleeved on the outside of the upper extension plate 135a. The fit between the upper extension and the lower extension plate defines the position of the cover 14 and prevents the cover 14 from shifting.

[0121] In one possible implementation, a connecting seat 1353 is provided on the cover fitting frame 135. A connecting ear 141 is provided on the edge of the cover 14. The connecting ear 141 is supported on the connecting seat 1353, and the connecting ear 141 and the connecting seat 1353 are detachably connected.

[0122] For example, a fixing hole is provided on the connector 1353, and a through groove is provided on the connector ear 141. One end of the fastener passes through the through groove and is connected to the fixing hole.

[0123] The through groove can be elongated, which solves the problem of misalignment between the through groove and the fixing hole caused by manufacturing errors.

[0124] In one possible implementation, a light-transmitting groove is formed in the middle of the cover 14, and a light-transmitting plate 142 is connected to the cover 14, covering the light-transmitting groove. Through the design of the light-transmitting plate 142, sunlight can pass through it and illuminate the battery swapping compartment 100, resulting in better lighting inside the battery swapping compartment 100.

[0125] In one possible implementation, see Figure 10 As shown, the cover 14 is provided with a lifting engagement part 143, which facilitates lifting the cover 14 by lifting equipment. The lifting engagement part may include multiple handles provided on the cover 14.

[0126] In one possible implementation, see Figure 7As shown, the sidewall includes a first sidewall 111 and two second sidewalls 112, which are spaced apart. The first sidewall 111 connects to the two second sidewalls 112. The top wall 13 connects to the first sidewall 111 and the two second sidewalls 112. The first sidewall 111 and the second sidewalls 112 enclose the cavity. The side of the battery swapping compartment 100 opposite to the first sidewall 111 is an open side. The open side is used to connect to the charging compartment, which is used to load battery boxes and chargers for charging the battery boxes. A doorway is provided on the first sidewall 111. The telescopic arm of the battery swapping robot can extend out of the open side to grab the battery boxes in the battery swapping compartment 100, and can retract and extend further out of the doorway to load the battery boxes onto the battery swapping vehicle. The battery swapping robot can transfer the battery boxes on the battery swapping vehicle to the charging compartment for charging, and transfer the fully charged battery boxes in the charging compartment to the battery swapping vehicle. The battery swapping robot has a telescopic arm and a gripper located at the end of the telescopic arm. The telescopic arm can drive the gripper to extend and retract, grabbing or releasing the battery box. The battery swapping robot has been patented, and its specific structure will not be described in detail here. Furthermore, various forms of battery swapping robots are applicable to this application, and this application does not limit the specific structure of the battery swapping robot.

[0127] Example 4

[0128] See Figures 12 to 18 As shown in the illustration, this application provides a more detailed description of the battery swapping compartment for a battery swapping device. The compartment includes a casing 1, a door 2, and a battery swapping robot (not shown). The casing 1 encloses a cavity and has a side wall 11 with a doorway 12 communicating with the cavity. The doorway 2 is connected to the side wall 11 and is used to open or close the doorway 12. The battery swapping robot is movably disposed within the casing 1. The battery swapping compartment provided in this application has a casing 1 to protect the internal battery swapping robot, preventing it from being exposed to the environment, and also protecting the battery box grasped by the robot. The doorway 12 on the casing 1 facilitates the extension of the multi-stage telescopic arm of the battery swapping robot to grasp or unload the battery box. The side of the battery swapping compartment facing away from the doorway is an open side, communicating with a charging compartment. The charging compartment stores the battery box and contains a charger for charging the battery box. The battery swapping robot transports the battery boxes from the vehicle to be swapped to the charging compartment for charging, and then transports the fully charged battery boxes from the charging compartment to the vehicle to be swapped. The robot has multi-stage telescopic arms and grippers at the ends of the telescopic arms. The multi-stage telescopic arms drive the grippers to extend and retract, grasping or releasing the battery boxes. The battery swapping robot is patented; its specific structure will not be described in detail here. Furthermore, various forms of battery swapping robots are applicable to this application, and this application does not limit the specific structure of the battery swapping robot.

[0129] In one possible implementation, see Figure 13As shown, the housing 1 is provided with a slide rail 3, and the door 2 is slidably connected to the slide rail 3. The door 2 can slide along the slide rail 3 to open or close the door opening 12.

[0130] The sliding rail 3 can extend along the length of the side wall. Part of the sliding rail 3 is located at the top or bottom of the doorway, and part extends to other positions on the side wall. The door body slides along the sliding rail 3 to open or close the doorway. The door body 2 can be a single door or a double door structure.

[0131] In one possible implementation, slide rails 3 are respectively provided on the upper and lower sides of the door opening 12 on the shell 1, and the upper and lower sides of the door 2 are slidably connected to the two slide rails 3 respectively.

[0132] In this implementation scheme, slide rails 3 are installed at both the upper and lower parts of the casing 1 to improve the support stability of the door 2. This facilitates the smooth opening or closing of the doorway 12.

[0133] In one possible implementation, a roller assembly 21 is provided on the door body 2, and the slide rail 3 has a track groove, in which the roller assembly 21 is accommodated.

[0134] In this implementation scheme, the roller assembly 21 on the door 2 is slidably supported within the track groove, which defines the position of each roller assembly 21, preventing the roller assembly 21 from disengaging from the slide rail 3. The design of the roller assembly 21 reduces the sliding resistance of the door 2.

[0135] In one possible implementation, the roller assembly 21 includes a bracket 211, a first roller 212, and a second roller 213. The bracket 211 is connected to the door body 2, and both the first roller 212 and the second roller 213 are connected to the bracket 211. The rotation axes of the first roller 212 and the second roller 213 are perpendicular to each other. The rolling surface of the first roller 212 contacts the bottom wall of the track groove, and the rolling surface of the second roller 213 contacts the side wall 11 of the track groove.

[0136] In this implementation scheme, the rotation axes of the first roller 212 and the second roller 213 are perpendicular. The first roller 212 is supported on the bottom wall of the track groove, and the second roller 213 is supported on the side wall 11 of the track, thereby limiting the door body 2 in two directions. The door body 2 has a stable assembly structure and is not easy to shake. During the opening and closing process, the noise generated by the sliding of the door body 2 is small.

[0137] In one possible implementation, both the slide rail 3 and the door 2 are located inside the cavity, making the external structure of the housing 1 flat and preventing external debris from easily entering the track groove of the slide rail 3. The door 2 and the slide rail 3 can maintain a good sliding fit.

[0138] In one possible implementation, see Figure 14 As shown, the battery swapping compartment also includes a drive mechanism 4, which is connected to the door 2 and drives the door 2 to open or close the door opening 12.

[0139] In this implementation scheme, the drive mechanism 4 can automatically drive the door 2 to open or close, and the degree of automation is high.

[0140] In one possible implementation, the door body 2 is provided with a hinge seat 22 along one side edge of the sliding direction, and the drive mechanism 4 has a telescopic end that is hinged to the hinge seat 22.

[0141] The driving component may include a telescopic cylinder, the end of which is hinged to a hinge seat 22 at the end of the door body 2. The telescopic cylinder extends and retracts, electrically moving the door body 2 along the slide rail 3. Of course, other driving mechanisms may also be used.

[0142] In one possible implementation, the drive mechanism 4 is connected to the side wall 11, which facilitates direct connection to the door body 2 and simplifies the connection structure.

[0143] In one possible implementation, the sidewall 11 has reinforcing longitudinal ribs and a skin covering the reinforcing longitudinal ribs. The drive mechanism 4 also includes a fixing beam 41, which is vertically connected to a plurality of the reinforcing longitudinal ribs. The fixing beam 41 and the plurality of reinforcing longitudinal ribs are connected and fixed, improving the stability of the assembled structure. The fixing beam 41 and the reinforcing longitudinal ribs can be fixed by welding or by fasteners, such as screws.

[0144] In one possible implementation, the telescopic mechanism includes a fixed part 42 and a telescopic part 43. The fixed part 42 is connected to the fixed beam 41, and the telescopic part 43 is connected to the door body 2. The telescopic mechanism may include a telescopic cylinder. The fixed part 42 may be the cylinder barrel of the telescopic cylinder, and the telescopic part 43 may be a telescopic rod connected to the cylinder barrel. The cylinder barrel may be fixed parallel to the fixed beam 41, and the end of the telescopic part is connected to a hinge seat 22 on the door body 2.

[0145] In one possible implementation, see Figures 16 to 18As shown, the casing 1 is equipped with a closed-position sensor 5 and an open-position sensor 6, which can be located on opposite sides of the doorway. The door body 2 is equipped with a first trigger 23 and a second trigger 24. The door body 2 has a closed position (closing the doorway 12) and an open position (opening the doorway 12). When the door body 2 slides to the closed position, the first trigger 23 triggers the closed-position sensor 5. When the door body 2 slides to the open position, the second trigger 24 triggers the open-position sensor 6. In this embodiment, automatic control of opening and closing the door body 2 can be achieved by setting two triggers and two position sensors. The control module is electrically connected to the drive mechanism 4, the closed-position sensor 5, and the open-position sensor 6. Upon receiving an opening command, the control module controls the retraction cylinder of the drive mechanism 4 to retract, moving the door body 2 until the second trigger 24 triggers the open-position sensor 6, at which point the control module controls the drive mechanism 4 to stop moving. Upon receiving a closing command, the control module controls the extension cylinder of the drive mechanism 4 to extend, moving the door 2 until the first trigger 23 triggers the closing position sensor. At this point, the control module stops the drive mechanism 4. The closing position sensor 5 and the opening position sensor 6 can be proximity switches or photoelectric switches. When both sensors are proximity switches, the trigger 2 is activated when it approaches the proximity switch, at which point the control module determines whether the door 2 has accurately reached the closed or open position. When both sensors are photoelectric switches, each sensor can include a transmitter and a receiver. The transmitter emits a signal, and the receiver receives the signal. When the trigger 2 moves between the transmitter and receiver, it blocks the receiver from receiving the signal, at which point the control module determines whether the door 2 has accurately reached the closed or open position.

[0146] Example 5

[0147] See Figures 19 to 24As shown in Embodiment 5 of this application, the charging compartment 200 of the battery swapping equipment is described in detail. The charging compartment 200 includes: a charging base box 210, an upper casing 230, and multiple chargers 220. The charging base box 210 has multiple lifting legs 2110, which are used to level the charging base box 210. Multiple battery box mounting bases 2120 are provided on the top of the charging base box 210. Each charger 220 is disposed inside the charging base box 210 and is electrically connected to the battery box mounting base 2120 to charge the battery boxes mounted on the battery box mounting base 2120. For example, the battery box mounting base 2120 has a charging terminal for charging the battery box, and the charger is directly electrically connected to this charging terminal. A power connection terminal is provided at the bottom of the battery box; when the battery box is mounted on the battery box mounting base, the charging terminal and the power connection terminal are directly electrically connected to achieve charging. The upper housing 230 is detachably connected to the charging base 210, and the upper housing 230 covers each of the battery box mounting bases 2120.

[0148] The charging compartment 200 of this application can not only temporarily store depleted battery boxes removed from the battery swapping vehicle, but also charge the removed depleted battery boxes without having to be transported to other stations for charging, thus reducing transportation costs. The upper shell 230 can cover the battery box mounting bases 2120, providing protection for the battery boxes and chargers 220.

[0149] In one possible implementation, see Figure 21 and Figure 22 As shown, the upper housing 230 and the charging base 210 enclose a battery storage cavity. A battery swapping clearance opening 233 communicating with the battery storage cavity is provided on one side of the upper housing 230. The upper housing 230 has a top wall 231, which is inclined. The side of the top wall 231 located near the battery swapping clearance opening 233 is higher, while the side of the top wall 231 furthest from the battery swapping clearance opening 233 is lower.

[0150] In this implementation, the top wall 231 is inclined to facilitate drainage and prevent rainwater from seeping into the charging compartment 200. The battery swapping device also has a battery swapping compartment, in which a battery swapping robot is installed, and a battery swapping avoidance opening 233 connects to the battery swapping compartment. In this application, the top wall 231 is positioned higher on one side of the battery swapping avoidance opening 233, preventing rainwater from flowing into the gap between the charging compartment 200 and the battery swapping compartment, thus avoiding a large amount of rainwater entering the battery swapping device and pouring onto the battery swapping robot performing its task, thereby improving safety.

[0151] In one possible implementation, see Figure 22 As shown, a water collection trough 2312a is provided on the top wall 231, and the water collection trough 2312a is located on the side of the top wall 231 away from the battery swapping avoidance opening 233.

[0152] During rainy or snowy weather, rainwater will flow along the top wall 231 into the water collection trough 2312a, which facilitates the smooth discharge of rainwater.

[0153] In one possible implementation, see Figure 21 and Figure 22 As shown, the upper housing 230 has side walls, and the top wall 231 includes a main body 2311 and a water collection plate 2312. The main body 2311 is connected to the side wall, and the battery swapping clearance opening 233 is formed between the main body 2311 and the side wall. The water collection plate 2312 is connected to the side wall, and the water collection plate is located on the side of the main body 2311 away from the battery swapping clearance opening 233. The water collection plate 2312 has the water collection groove 2312a. The main body 2311 is inclined from the side of the battery swapping clearance opening 233 towards the side of the water collection plate 2312.

[0154] In one possible implementation, the charging compartment 200 further includes a drain pipe 240 connected to the water collection tank 2312a. Liquid accumulated in the water collection tank 2312a can be drained through the drain pipe 240.

[0155] In one possible implementation, the upper housing 230 is provided with adapter boxes 250 at both ends of the water collection tank 2312a, the adapter boxes 250 are connected to the water collection tank 2312a, and the drain pipe 240 is connected to the adapter boxes 250.

[0156] In this implementation scheme, the adapter box 250 serves as a buffer and confluence point. The design of the adapter box 250 facilitates the connection of the drain pipe 240 to the water collection tank and makes the connection and assembly of the drain pipe 240 easier.

[0157] In one possible implementation, see Figure 22 As shown, the upper housing 230 is provided with a plurality of fasteners 260 for fixing the drain pipe 240, and each fastener 260 is arranged at intervals along the length of the drain pipe 240. The two ends of the fasteners are fixed to the upper housing 230, and the middle part is pressed against the drain pipe 240.

[0158] In one possible implementation, see Figure 19 and Figure 20 As shown, the charging base box 210 is provided with a guide component 2130. During the process of the upper box shell 230 being installed into the charging base box 210, the upper box shell 230 slides along the guide component 2130 until it is supported on the charging base box 210.

[0159] In this implementation scheme, the guide component 2130 facilitates accurate assembly of the upper housing. A lifting ring can be installed on the upper housing for lifting and lowering using hoisting equipment.

[0160] In one possible implementation, the guide component 2130 has an upwardly convex arc-shaped guide surface, and the bottom of the upper housing 230 is provided with a guide mating hole 232. During the process of installing the upper housing 230 onto the charging base box 210, the guide component 2130 can be inserted into the guide mating hole 232.

[0161] In one possible implementation, the charging base 210 has an upper wall, and the lifting leg 2110 has a supporting shell with a flat top wall that is higher than the upper wall. When the upper shell 230 is installed in the charging base 210, the upper shell 230 is supported by the flat top wall, and there is a gap between the upper shell 230 and the upper wall. The gap between the bottom surface of the upper shell 230 and the top surface of the upper wall prevents manufacturing errors from affecting assembly.

[0162] In one possible implementation, see Figure 23 and Figure 24 As shown, the charging compartment 200 also includes an exhaust duct 215. The charging base box 210 has a cavity, the exhaust duct 215 is disposed in the cavity, and each of the chargers 220 is disposed in the cavity. Each of the chargers 220 is connected to the exhaust duct 215.

[0163] The heat generated by the charger 220 enters the exhaust duct 215 and is eventually discharged from the charging base box 210, ensuring that the charging base box 210 operates at a low temperature, so that the charger 220 can maintain good working conditions.

[0164] In one possible implementation, each charger 220 is disposed on both sides of the exhaust duct 215, and the chargers 220 are arranged sequentially along the length of the exhaust duct 215. The chargers 220 are disposed on both sides of the exhaust duct 215 and are arranged neatly, making full use of the internal space.

[0165] Multiple battery box mounting bases are arranged along the length of the top of the charging base box 210, and each charger inside the charging base box 210 is electrically connected to each of the battery box mounting bases via power supply cables.

[0166] In one possible implementation, see Figure 24 As shown, the bottom of the exhaust duct 215 is connected to a bracket 216, which supports the exhaust duct 215. The exhaust duct 215 has a bottom wall with multiple connecting ports, and each charger 220 is connected to a corresponding connecting port on the bottom wall.

[0167] In this implementation scheme, the exhaust pipe is suspended by the bracket 216, which facilitates the connection of the charger 220 to the connection port on the bottom wall through the pipe. The width dimension occupied by all the chargers 220 and exhaust pipes 215 in the battery swapping equipment is small, which helps to reduce the width of the charging base box 210.

[0168] In one possible implementation, the charging compartment 200 includes two exhaust ducts 215, which are arranged sequentially along the length of the charging base box 210. Each exhaust duct 215 is equipped with an air outlet and a fan. By providing two exhaust ducts 215, the extension length of each exhaust duct is shortened, which facilitates faster airflow under the same fan drive.

[0169] In one possible implementation, the charging base box 210 is provided with a grid window 214 corresponding to each of the exhaust ducts 215, and each of the exhaust ducts 215 extends to the corresponding grid window 214 and is provided with the air outlet at its end.

[0170] In this implementation scheme, the design of the grid window 214 facilitates the direct discharge of hot air to the outside through the air outlet at the end of the exhaust pipe.

[0171] Example 6

[0172] Embodiment 2 of this application provides a battery swapping method for the above-mentioned battery swapping equipment, including:

[0173] Step S1: The battery swapping robot moves to the battery swapping station and grabs the depleted battery box on the vehicle to be swapped.

[0174] Step S2: The battery swapping robot travels along the set trajectory to the battery box temporary storage seat and puts the depleted battery box into the battery box temporary storage seat;

[0175] Step S3: The battery swapping robot moves along the set trajectory to the position corresponding to the target fully charged battery box and grabs the target fully charged battery box;

[0176] Step S4: The battery swapping robot moves to the battery swapping station and loads the target fully charged battery box into the battery swapping vehicle.

[0177] Optionally, the battery swapping method of the battery swapping equipment includes two battery storage seats, with a battery swapping station between the two battery storage seats;

[0178] In step S2, the battery swapping robot transfers the depleted battery box to one of the battery box temporary storage seats;

[0179] In step S3, the battery swapping robot moves to the side where the other battery box temporary storage seat is located until it reaches the target fully charged battery box.

[0180] Optionally, the gripping mechanism includes a multi-stage telescopic boom and a gripper, wherein the gripper is connected to the end of the multi-stage telescopic boom;

[0181] In step S1, the gripping mechanism can extend in the first direction to grip the depleted battery box on the vehicle to be swapped.

[0182] In step S2, the gripping mechanism can retract to transfer the depleted battery box to the battery box temporary storage seat;

[0183] In step S3, the gripping mechanism can extend in the second direction to grip the target fully charged battery box;

[0184] The first direction and the second direction are two opposite directions perpendicular to the set trajectory.

[0185] Step S4 is followed by step S5: the battery swapping robot moves to the battery box storage seat where the depleted battery boxes are stored, and picks up the depleted battery boxes and puts them into the corresponding battery box fixing seat in the charging compartment.

[0186] The battery swapping robot has been patented, and its specific structure will not be described in detail in this application. Moreover, various forms of battery swapping robots can be applied to this application, and this application does not limit the specific structure of the battery swapping robot.

[0187] The battery swapping robot's gripping mechanism also includes a lifting mechanism, which is located at the end of the multi-stage telescopic boom. The gripper is connected to the lifting mechanism, which drives the gripper to move up and down, allowing it to grab or release the battery box. The battery box mounting base needs to charge the battery box and hold it in place for extended periods, therefore it has a locking mechanism and a charging connector, making its structure relatively complex. In contrast, the battery box storage base only needs to temporarily store the battery box, eliminating the need for a locking mechanism and electrical connector, resulting in a much simpler structure and reducing the cost of the battery swapping equipment.

[0188] When a battery box needs to be grasped, the multi-stage telescopic boom extends and retracts, positioning the gripper directly above the battery box. The lifting mechanism then lowers the gripper to contact and grasp the battery box. Subsequently, the lifting mechanism raises the gripper, lifting the battery box. When the battery box needs to be transferred to a battery box mounting base or temporary storage location, the multi-stage telescopic boom first retracts the battery box. Then, the entire battery swapping robot moves along a pre-set trajectory to the target position. The multi-stage telescopic boom extends again, positioning the gripper directly above the corresponding battery box temporary storage location or mounting base. The lifting mechanism then lowers the gripper, loading the battery box into the battery box temporary storage location or mounting base, and the gripper releases the battery box.

[0189] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
